The "Gold Barb", "Puntius semifasciolatus"
is an excellent little aquarium fish. It usually grows to about two
inches long (5cm) although I have seen ones nearer 4 inches (10cm). The Gold Barb is from Asia but the actual Gold form does not exist in the wild. Their usual life span is about five years.
Naming Confusion
This
fish has many names. Other Common names are "Golden Barb", "Schubert's
Barb", "Green Barb", "Half Stripped Barb", "China Barb", "Chinese Half
Stripped Barb" and "Six Banded Barb". Other Scientific names it has
been known by include: "Barbus semifasciolatus", "Pontius Shubertii", "Puntius Shubertii", "Barbus Shubertii" and "Capoeta semifasciolatus"".
To add to the naming perplexity, the Gold Barb is often confused with: the "Golden Barb" (Puntius gelius) or the "Gold-finned Barb" (Puntius sachsii). The species name "Shubertii"
refers to Tom Shubert of Camden, New Jersey, USA who developed the Gold
Barb. He did this by selective breeding, presumably from the wild form
of Puntius semifasciolatus, in the 1960's. I remember when I was a teenager keeping fish in the 1960's and later that the Gold Barb
was called Barbus Shubertii. It was believed by some people to be a
distinct species although there was already a suspicion that it was a
form of Puntius semifasciolatus. I do not think that Barbus Shubertiiwas ever a valid scientific name. Water Conditions
The Gold barb thrives in cooler water than most tropical fish. 18 - 24° C
(64 - 75° F) is this fish's preferred range although it will certainly
survive several degrees above this and a few degrees below. This means
that it is suitable for either a tropical aquarium with the temperature
set at 24° C (75° F) or an unheated tank in areas that do not get very
cold. It is interesting to note that the color change was not the only
change that happened when Mr. Shubert was breeding these fish. The Gold
form of the species is a little less cold resistant than the wild type.The wild type is sometimes sold as the "China Barb" and is a good aquarium fish although not as attractively colored as the Gold Barb.
The Gold Barb likes fairly soft, slightly acidic water, but does well over
a range of pH. I usually aim for neutral (7). It will tolerate a
moderate amount of hardness in the water.
Food
The Gold Barb is an easily fed omnivore. Any good quality fish food is an
excellent basis for its diet. As with nearly all fish, and most other
animals, the Gold Barb benefits from the occasional change in its diet.
Live food like mosquito larvae and Daphnia are gobbled up greedily.
Frozen blood worms also make a good treat.
Companions
The Gold Barb is a schooling fish and a minimum of six should be kept.
The Gold Barb is not as likely to become a fin nipper like Rosy Barbs, and Tiger Barbs,
but can be kept with these fish as well as with other slightly
aggressive fish like Paraguay Tetras, Buenos Aires Tetras and Colombian
Tetras. Because the Gold
Barb is peaceful it can also be kept with fish like Pristella Tetras,
Rummy Nose Tetras , Harlequin Rasboras, Scissortail Rasboras, Lemon
Tetras , Black Widow Tetras, Emperor Tetras, Head and Tail Light
Tetras, Glass Bloodfin Tetras, Swordtails, Platies, Mollies, Zebra
Danios, Glowlight Tetras, White Cloud Mountain Minnows and Cherry Barbs
as well as the Corydoras catfish like the Peppered Catfish. I would not recommend them as companions for Siamese Fighting Fish, Guppies and Endlers Guppies. Small fish like Neon Tetras and Cardinal Tetras
can certainly be kept with smaller Gold Barbs. In all cases, avoid too
great a size difference between the fish in your aquarium.
Do not put large, aggressive or predatory fish with Gold Barbs. Breeding
Gold
Barbs scatter their eggs over plants, preferably fine leaved ones. The
males tend to be brighter in color and when ready to breed will get an
orange-red belly. The females are duller in color and plumper.
An increase in temperature to about 27̊ C (80̊ F) as well as a drop in pH to about 6.5 will tend to encourage them to breed.
The spawning can be a little violent, so the tank should be reasonably big. I suggest at least two feet (60cm) long.
The
actual spawning will usually take place when the tank starts to get
light in the morning. I suggest removing the parents immediately after
spawning. The average number of eggs per female is about a hundred
although I have known of a female that produced over 400 eggs at one
spawning.
An alternative way of breeding Gold Barbs is to have
them in as big an aquarium as possible, with large numbers of plants
and leave the parents in. Of course you are likely to get less babies
surviving, but this is a little closer to what could happen in the
wild. A variation on this method is to put them into a well planted
pond in the summer months and catch all the fish before it get too cold
in the autumn (fall).
The eggs are a yellowish color. They
should hatch in 2-3 days. The fry will eat fine dry foods, but benefit
from suitable sized live foods at all stages.
Pest Fish
As with all captive fish, do release your Gold Barbs into the wild and do not put them in a situation where they could get out.
